The solubility product of nickel (II) hydroxide at 25°C is 1.6 x 10-16.
a) Calculate the molar solubility of nickel (II) hydroxide in pure water at 25°C.
b) Calculate the molar solubility of nickel (II) hydroxide in 0.100 M sodium hydroxide.
This is a fairly straight forward two problems. Tell us what you don't understand about a, then b. Perhaps we can help you through them.
